Explanation / Answer

Q1.

fatty acids --> are acids which contain an acid group + long hydrocarbon chain

fat --> typically composed of three long hydrocarbon chains, they all contain ester gropus C-O-C=O group

Q2.

sat. fat vs. unsat fat.

saturated --> will contain more Hydrogens, no double bonds, higher melting points, heavier in mass

unsaturated --> less Hydrogens, due to at least 1 or 2 double bonds, lower melting points, light in mass

Q3.

saponification will get a glycerol + 3 soap molecules from the fat + base

the strong base helps in this process

Q4.

saponification produces salt since there is presence of astrong base, such as NaOH, and the ionization of the R1-COO- ion

Q5.

the structure changes mainly in double bonds vs. non double bonds. Saturated, as the name implies, states plenty of Hydrogen in carbon chain
